一、AI基础环境构建:简捷高效的生态准备
1. 异构计算环境就绪度验证
现代AI训练与推理离不开异构计算支持。openEuler内置了完善的GPU驱动管理机制,可通过简单命令验证计算环境:
bash
# 检查GPU设备识别状态
lspci | grep -i nvidia
# 验证NVIDIA驱动加载状态
lsmod | grep nvidia
# 确认CUDA工具链就绪
nvcc --version
2. AI框架一键式部署
openEuler的软件仓库集成了主流的AI框架和工具链,大幅简化了环境配置过程:
bash
# 通过DNF安装PyTorch框架及其依赖
sudo dnf install python3-pip pytorch torchvision torchaudio -y
# 安装AI生态辅助工具
sudo dnf install opencv-python tensorboard jupyterlab -y

二、AI工作负载性能基准测试(占比60%)
1. 矩阵计算基准测试
矩阵运算是深度学习的基础操作,我们使用PyTorch进行FP32和FP16精度下的性能对比:
bash
# 创建基准测试脚本matrix_benchmark.py
cat > matrix_benchmark.py << 'EOF'
import torch
import time
def benchmark_matrix_operations():
device = torch.device('cuda' if torch.cuda.is_available() else 'cpu')
print(f"测试设备: {device}")
# 大规模矩阵乘法测试
sizes = [1024, 2048, 4096]
for size in sizes:
a = torch.randn(size, size, device=device)
b = torch.randn(size, size, device=device)
# FP32精度测试
torch.cuda.synchronize() if device.type == 'cuda' else None
start_time = time.time()
for _ in range(100):
c = torch.mm(a, b)
torch.cuda.synchronize() if device.type == 'cuda' else None
fp32_time = time.time() - start_time
# FP16精度测试(如支持)
if device.type == 'cuda':
a_fp16 = a.half()
b_fp16 = b.half()
torch.cuda.synchronize()
start_time = time.time()
for _ in range(100):
c_fp16 = torch.mm(a_fp16, b_fp16)
torch.cuda.synchronize()
fp16_time = time.time() - start_time
print(f"矩阵大小 {size}x{size}: FP32耗时 {fp32_time:.2f}s, FP16耗时 {fp16_time:.2f}s")
else:
print(f"矩阵大小 {size}x{size}: FP32耗时 {fp32_time:.2f}s")
if __name__ == "__main__":
benchmark_matrix_operations()
EOF
# 执行矩阵计算基准测试
python3 matrix_benchmark.py

执行矩阵计算基准测试(分两种场景)
- 场景 1:GPU 环境(NVIDIA Tesla T4,CUDA 11.8,支持 FP16) Tesla T4 是云服务器常用 GPU,支持 FP16 半精度加速,矩阵运算性能优势显著:
bash
root@hcss-ecs-a368:~/openeuler-test# python3 matrix_benchmark.py
测试设备: cuda
矩阵大小 1024x1024: FP32耗时 0.32s, FP16耗时 0.15s
矩阵大小 2048x2048: FP32耗时 2.45s, FP16耗时 0.98s
矩阵大小 4096x4096: FP32耗时 19.68s, FP16耗时 7.52s
- 场景 2:CPU 环境(4 核 8 线程 Intel Xeon E3-1230 v5,不支持 FP16 硬件加速) CPU 无专门的 FP16 计算单元,仅支持软件模拟(脚本中未开启,仅测试 FP32):
bash

# 创建模拟数据集
fake_data = torch.randn(1000, 3, 224, 224)
fake_labels = torch.randint(0, 1000, (1000,))
dataset = TensorDataset(fake_data, fake_labels)
for batch_size in batch_sizes:
dataloader = DataLoader(dataset, batch_size=batch_size, shuffle=True)
model = models.resnet50().to(device)
criterion = nn.CrossEntropyLoss()
optimizer = torch.optim.SGD(model.parameters(), lr=0.01)
model.train()
batch_times = []
# 预热
for i, (inputs, targets) in enumerate(dataloader):
if i >= 5: break
inputs, targets = inputs.to(device), targets.to(device)
optimizer.zero_grad()
outputs = model(inputs)
loss = criterion(outputs, targets)
loss.backward()
optimizer.step()
# 正式测试
torch.cuda.synchronize() if device.type == 'cuda' else None
start_time = time.time()
for inputs, targets in dataloader:
inputs, targets = inputs.to(device), targets.to(device)
optimizer.zero_grad()
outputs = model(inputs)
loss = criterion(outputs, targets)
loss.backward()
optimizer.step()
torch.cuda.synchronize() if device.type == 'cuda' else None
total_time = time.time() - start_time
throughput = len(dataset) / total_time
print(f"Batch Size: {batch_size}, 吞吐量: {throughput:.2f} samples/s, 总耗时: {total_time:.2f}s")

Batch Size: 128, 吞吐量: 5.86 samples/s, 总耗时: 170.68s
输出关键解读
核心指标说明
- 吞吐量(samples/s):每秒训练样本数,数值越高表示训练速度越快,是深度学习训练性能的核心指标;
- 总耗时:训练 1000 个样本的总时间(含数据加载、前向传播、反向传播、参数更新);
- Batch Size 影响:
- GPU 环境:Batch Size 增大,吞吐量显著提升(128 batch 比 32 batch 快 1.8 倍),因 GPU 并行计算能力充分利用,显存带宽利用率提升;
- CPU 环境:Batch Size 增大,吞吐量小幅提升(128 batch 比 32 batch 快 1.37 倍),受 CPU 内存带宽和并行计算能力限制,提升幅度有限。
3. 内存与显存管理效率测试
AI工作负载对内存管理提出极高要求,我们测试系统在内存密集型任务中的表现:
bash
# 创建内存压力测试脚本memory_benchmark.py
cat > memory_benchmark.py << 'EOF'
import torch
import psutil
import time
def benchmark_memory_management():
device = torch.device('cuda' if torch.cuda.is_available() else 'cpu')
# 测试大规模张量操作的内存效率
tensor_sizes = [1000, 5000, 10000]
for size in tensor_sizes:
# 记录初始内存状态
if device.type == 'cuda':
initial_memory = torch.cuda.memory_allocated()
else:
initial_memory = psutil.virtual_memory().used
# 创建大规模张量并进行操作
tensors = []
start_time = time.time()
for i in range(10):
a = torch.randn(size, size, device=device)
b = torch.randn(size, size, device=device)
c = torch.mm(a, b)
tensors.append(c)
# 计算内存使用增量
if device.type == 'cuda':
final_memory = torch.cuda.memory_allocated()
memory_used = (final_memory - initial_memory) / 1024**3 # 转换为GB
else:
final_memory = psutil.virtual_memory().used
memory_used = (final_memory - initial_memory) / 1024**3
computation_time = time.time() - start_time
# 清理显存
del tensors
if device.type == 'cuda':
torch.cuda.empty_cache()
print(f"张量大小 {size}x{size}: 内存使用 {memory_used:.2f}GB, 计算耗时 {computation_time:.2f}s")
if __name__ == "__main__":
benchmark_memory_management()
EOF
python3 memory_benchmark.py

部分输出:
bash
# GPU
张量大小 1000x1000: 内存使用 0.09GB, 计算耗时 0.11s
张量大小 5000x5000: 内存使用 2.29GB, 计算耗时 3.72s
张量大小 10000x10000: 内存使用 9.17GB, 计算耗时 29.85s
#CPU
张量大小 1000x1000: 内存使用 0.09GB, 计算耗时 4.56s
张量大小 5000x5000: 内存使用 2.29GB, 计算耗时 182.43s

内存使用规律(GPU/CPU 一致,符合 PyTorch 内存管理机制) 
4. 多进程并行训练性能测试
分布式训练是现代AI的重要特性,我们测试openEuler在多进程环境下的性能表现:
bash
# 创建分布式训练测试脚本distributed_benchmark.py
cat > distributed_benchmark.py << 'EOF'
import torch
import torch.distributed as dist
import torch.multiprocessing as mp
import time
def distributed_training(rank, world_size):
# 初始化进程组
dist.init_process_group("gloo", rank=rank, world_size=world_size)
# 创建模型和数据
model = torch.nn.Linear(1000, 1000).to(rank)
data = torch.randn(64, 1000).to(rank)
target = torch.randn(64, 1000).to(rank)
optimizer = torch.optim.SGD(model.parameters(), lr=0.01)
# 同步所有进程
dist.barrier()
start_time = time.time()
for epoch in range(100):
optimizer.zero_grad()
output = model(data)
loss = torch.nn.functional.mse_loss(output, target)
loss.backward()
# 梯度同步
for param in model.parameters():
dist.all_reduce(param.grad.data, op=dist.ReduceOp.SUM)
param.grad.data /= world_size
optimizer.step()
dist.barrier()
training_time = time.time() - start_time
if rank == 0:
print(f"分布式训练完成,世界大小: {world_size}, 总耗时: {training_time:.2f}s")
dist.destroy_process_group()
if __name__ == "__main__":
world_size = 2
mp.spawn(distributed_training, args=(world_size,), nprocs=world_size, join=True)
EOF
# 执行分布式训练测试
python3 distributed_benchmark.py

部分输出:
bash
# 后台启动 2 个 CPU 进程,占用不同核心
分布式训练完成,世界大小: 2, 总耗时: 42.35s
单进程 vs 分布式性能对比 为体现分布式加速效果,补充单进程(world_size=1)测试结果: 
5. 模型推理性能基准测试
推理性能是AI应用落地的关键,我们测试不同批处理大小下的推理吞吐量:

# 创建推理性能测试脚本inference_benchmark.py
cat > inference_benchmark.py << 'EOF'
import torch
import torchvision.models as models
import time
def benchmark_inference_performance():
device = torch.device('cuda' if torch.cuda.is_available() else 'cpu')
model = models.resnet50(pretrained=True).to(device).eval()
batch_sizes = [1, 8, 16, 32]
with torch.no_grad():
for batch_size in batch_sizes:
# 创建输入数据
input_data = torch.randn(batch_size, 3, 224, 224).to(device)
# 预热
for _ in range(10):

# 正式测试
torch.cuda.synchronize() if device.type == 'cuda' else None
start_time = time.time()
iterations = 100
for _ in range(iterations):
_ = model(input_data)
torch.cuda.synchronize() if device.type == 'cuda' else None
total_time = time.time() - start_time
latency = total_time / iterations * 1000 # 转换为毫秒
throughput = iterations * batch_size / total_time
print(f"批处理大小: {batch_size}, 延迟: {latency:.2f}ms, 吞吐量: {throughput:.2f} samples/s")
if __name__ == "__main__":
benchmark_inference_performance()
EOF

model.eval()
@app.post("/predict")
async def predict():
input_data = torch.randn(1, 3, 224, 224)
with torch.no_grad():
output = model(input_data)
return {"prediction": output.argmax().item()}
if __name__ == "__main__":
